A nickel-catalyzed intramolecularnucleophilicaddition reaction of aryl halides to arylketones for the formation of benzofuran derivatives has been developed. A number of substrates bearing electron-donating or electron-withdrawing groups were subjected to the standard reaction conditions, giving the corresponding products in moderate to good yields.
